Hi
Thanks for your reply I tried your instructions. When I go to playback settings the audio output is sndpipcm5102A.
There is still no sound from the DAC!
Is there anything else I should try?
Cheers

Hi,
I tried to connect Raspberry to Najda
diyaudio.com/forums/digital- … t-2-a.html
waf-audio.com/products.php?pos=1&lang=en
and have the same issue. Volumio stay in pause if I check the I2S box.
Did you solve?

Check on hifiberry website a topic configure your linux system, ans see if you have all the modules listed on their website on your /etc/modules. I successfully connected NOS tda1543T module on volumio. Don’t switch i2s on from volumio gui after you check if you have all the modules in /etc/modules, because it will overwrite your modules.Wich version of volumio do you have?

hi birca I could try this way, but before I think I will have to install version 1 beta because I read some posts on diyaudio saying that in version 1.1 I2S is not working properly.
which version do you use?
V
Install v1.1 and after that do what is on this website , don’t turn i2s on from volumio gui. hifiberry.com/products/dac/h … -software/

Or do this https://community.volumio.com/t/activating-of-hifiberry-dac-without-web-ui/334/16

Thankyou Birca,
I modified /etc/modules and now it is OK.

Hi,
I followed the instructions on the hifiberry website and modified the 1.1 software.
Now with my TDA1541a DAC connected to P5 I get static interference from the speakers when I press play. So at least there is something coming out the speakers, but not music!
Is there something different about the TDA1541a that means I need to make some other changes to get this to work?
I must be getting close.
I am grateful for all advice.
cheers
Ian
I have been battling on trying to get the Raspberry pi and volumio to talk to my TDA1541A DAC. Today I discovered that a new version of Volumio has appeared 1.2 which I downloaded and put on my Pi. The software seems to work ok, though I couldn’t configure my wireless and ended up using wicd-curses which worked fine. The bug that stopped I2S in version 1.1 appears to be fixed, in that the software does not stick in pause and hifiberry is listed as the DAC.
However, having doen all the configuration and wired it up to my DAC it still does not work. I will be interested to see if others have any more success than me.
From what I have read so far and the feedback to this thread, others have made the I2S work with their DAC’s but no one has stated that the I2S works with the TDA1541a. So this coupled with my own observations leads me to the conclusion that unfortunately Volumio is unsuitable for use with this very special chip.
I will keep an eye out on different software options as for the time being I am going to give up with this as it simply does not work for my purpose.
Ian
where?

Hey Ian,
Are you sure the SCK should be connected to the BCK? thought it was a multiple of the sample rate. the TDA1543 doesn’t use the SCK so explains why that worked. Agree the 1541 is a special chip, perhaps look at the hifiberry digi for the SCK?
Whats the datasheet state?
Chuz,
Drew.

After some time away from my Pi I decided to investigate why I couldnt get the TDA1541a DAC to work through I2S. I checked the BCK, data and LRCK by looking at the signals on an oscilloscope. I found that there was no sign of any LRCK signal. I decided to give things another go and bought a new Pi. I checked the signals again on the scope and all three were present. So I connected the Pi to the TDA1541A DAC and it works!
I know others have had good success with other I2S DAC’s, but I am just delighted to get my system working. I havent had any time for critical listening, though on initial hearing there is no sign of crackles or any other obvious problems.
I used the latest version of Volumio 1.1. From what I could tell the bugs within the software were fixed as the /etc/modules/ were correct.
Cheers
Ian
Hey Ian
So what are you using for SCK to the dac?
Chuz,
Drew.
Hi Drew,
The TDA1541A doesn’t have SCK, it has; pin1 = LRCK, pin 2 = BCK, pin3 = Data, pin5 =gnd.
The TDA1541 has SCK. With the TDA1541 BCK, LRCK and data are the same pins as the TDA1541A, however, you connect pin 4 (DataR/SCK) to pin 2 (BCK), and it should work.
Now whilst I haven’t tried the TDA1541 with the volumio yet it should work as I have got it working with the I2S output of my CD transport. I have some TDA1541’s at home and might try tonightif I have time.
The other difference between the TDA1541 and the TDA1541A is that the TDA1541A requires an external oscillator cap between pins 16 and 17 (I cannot remember the value.
Hope that helps.
Cheers
Ian
Thanks Ian,
That in all seriousness is very enlightening, never noticed that before!
How is the sound progressing with the dac and Pi?
Chuz,
Drew.
Hi Drew,
I am just having the first proper listen to the Pi using a standard TDA1541A chip, the music coming from a USB drive plugged straight into the pi (WAV files) and first impressions are extremely positive.
I usually feed the DAC with a Philip CD-Pro 2M CD transport which is very highly rated (I believe it was used in some of the very high end Naim CD players) and I have always thought the CD player was extemely good. Comparing the Pi to the CD transport it is not yet apparent that the Pi is in anyway inferior to the CD player.
I built the DAC with an IC socket for the TDA chip so that I could experiment with different versions of the DAC chip and I am very fortunate to own a double crown version, which now I know the Pi works I will plug in and see if things improve further.
I have to say I thought I would have to reclock the I2S to get the jitter down to a suitably low level. However, based on what I am hearing now, I am not sure I need to bother. I will however try building a large linear powersupply for the Pi, currently it is using a 1A HTC phone supply and obviously this could be improved. Not sure it will make that difference to the sound but I wan to get it to be done properly.
Cheers
Ian
Hey Ian,
Excellent! I am looking for a Holland S1 or 2, if you come across 1 or 2…
Will hopefully be following your lead here soon, have a reclock already here, will be interesting to see what comes of it. Look at a linear choke loaded, feeding a ccs to a shunt reg power supply, you may be surprised at the difference…
Thanks for doing that testing, really appreciated!
Chuz,
Drew.
Ian,
Meant to ask, what dac build and system are you running!
Chuz,
Drew.
